Apprenticeship Test Preparation: Math, Spatial, and Mechanical Aptitude

Vocabulary practice flashcards covering test sections, spatial visualization concepts, mechanical principles, and arithmetic/algebra fundamentals from the apprenticeship preparation guide.

Apprenticeship Entrance Examination Components

The comprehensive four-part assessment consisting of: 1) Math, 2) Spatial Aptitude, 3) Mechanical Aptitude, and 4) General Knowledge.

Matching Parts and Figures

A spatial aptitude test format that requires visualizing the complete shape or pattern that results from assembling cut-up pieces together without overlapping edges or empty spaces.

Perceptual Ability

A measurement of an individual's powers of observation evaluated through exercises requiring comparing, contrasting, and ranking similar figures or objects.

Similarities and Differences Between Objects

A perceptual observation test where each problem presents five drawings lettered (A) through (E), four of which are identical while one contains a slight distinguishing difference.

Line Ranking and Angle Comparison Tests

Perceptual problem-solving tests designed to assess two-dimensional visual perception through comparative judgment of line lengths and angle measurements.

Mechanical Insight

An examination section that evaluates practical mechanical understanding, including threaded fasteners, vibrational frequency, load distribution, and kinematic motion.

Apparent Weight in an Elevator

The physical effect where a handheld load feels heaviest when the elevator is gaining speed in ascent due to upward acceleration adding to the gravitational force.

Natural Frequency of Vibrating Wires

The vibration frequency of acoustic or mechanical wires sharing identical material, diameter, and tension, which varies inversely with length such that shorter wires vibrate at higher frequencies.

Trajectory Minimum Speed Point

The position along an airborne projectile's path (such as a basketball) where total speed is at its lowest, occurring at the trajectory's apex where vertical velocity equals zero.

Cam and Follower Mechanism

A mechanical assembly where a follower rod is displaced by a rotating eccentric cam, attaining its maximum height or displacement at the lobe's greatest radial distance.

Load Distribution on Two Carriers

The mechanical principle of levers dictating that when two people carry a shared weight on their shoulders, the carrier positioned closer to the weight bears the larger share.

Order of Operations with Grouping

The algebraic evaluation rule illustrated by simplifying $\frac{10 - (8 + 7)}{-5}$, where evaluating inside parentheses yields $10 - 15 = -5$, resulting in $\frac{-5}{-5} = 1$.

Common Fraction in Lowest Terms

A fraction whose numerator and denominator share no common factors greater than $1$; for example, converting $0.085$ yields $\frac{85}{1000}$, which simplifies to $\frac{17}{200}$.

System of Linear Equations

A set of equations solved simultaneously; for example, subtracting $2p - q = 7$ from $3p - q = 10$ determines that $p = 3$, which substitutes to give $q = -1$.
